Throughout the world, Saydul (Saydul 
) is quite a rare predominantly male, but very infrequently female first name. The first name Saydul is habitual in Western Asia, particularly Oman, where it is quite a rare masculine name, Qatar, and Bahrain. Not in comparison with a country's population, this name is the most popular in Bangladesh, India, and Saudi Arabia. Much less frequently, Saydul is the last name as well as the forename.
